TUBE.

Application filed March 9, 1927; Serial No. 173,985.

lindrical extension with an opening having beveled walls so that a brush can be placed I in the opening to receive the material being ejected through the cap.

A still further object of the invention is to provide means for keeping the opening in the drum-like valve, when the valve is in closed position, in communication with the tube so that material in the opening will be kept moist by being in contact with the material in the tube.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying 30 drawings wherein like characters denote like or corresponding parts throughout the several views, and in which .Figure l is a top plan view of the improved cap.

Figure 2 is an elevation of portion of a tube, with the cap thereon.

Figure 3 is an end view of the cap.

Figure 4 is a section on line 4-4 of Figure 1.

Figure 5 is a section on line 55 of Figure 1.

Figure 6 is a View similar to Figure 5, but showing the valve in closed position.

As shown in these views, the cap A has its lower or inner portion 1 made a usual and threaded so that it can be screwed on the screw threaded neck of a tube B. A cylindrical extension 2 is formed on the upper or outer part of the cap1 with its axis arranged at right angles to t c axis of the cap, and

' this 'extension is formed with a cylindrical bore to receive the cylindrical drum-like valve 3. One end of this valve isformed with an enlar ed part 4 which is knurled on its circumference to form a handle so that the valve can be rotated, and as will be seen, this enlargement is of the same diameter as the outer diameter of the part 2. A groove 5 is formed in this enlargement and receives a projection 6 at one end of the lower part of the extension 2, this arrangement acting as a stop to limit the rotary movement of the valve. After the valve has been ut in the bore, its small end is upset, as at to hold it in place, yet permitting it to rotate.

A slot 8 places the part- 1 of the cap in communication with the cylindrical bore and an opening 9 having beveled walls is made in the top-or outer portion of the part 2, this opening acting. as a discharge opening for the cap and the slot 8 is in alignment with the opening; A passage or slot 10 is diametrically arranged in the valve and when the valve is in one position, this slot 10 will register with the slot -8 and opening 9 so that some of the contents of the tube can be discharged through the cap, as will be understood. Then by giving the valve a quarter turn, the opening 9 will be closed by a portion of the valve, as shown in Figure.

6, so that the tube will be closed and none of its contents can escape from the cap.

In order to prevent the material in the slot 10 from hardening when the valve is closed, I cut away or notch a portion of the drum 3, as shown at 11, which will place the slot 10 in communication with the interior of the part 1- when the valve is in closed position, as shown in Figure 6, so that the material in the slot 10 will be kept moist.

By beveling the walls of the opening 9, a toothbrush can be placed close to'the cap to receive the material being ejected from the tube.

From the foregoing it will be seen that I have provided a simple form of closure for a tube for paste and the like, it simply being necessary to give the valve member a quarter turn to open the same and another quarter turn in a reverse direction to close the same. As the cap is not removed from the tube, there is no danger of losing the cap and it can be opened and closed in the minimum amount of time.

If desired, the cap can be removed from an empty tube and placed on a filled one so that it will not be necessary to furnish my improved cap with each tube, though, of course, it will be understood that this latter course is preferable.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is:

A'- cap for a tube having a cap-shaped inner portion for detachably engaging the neck of a tube and a cylindrical outer portion having its axis arranged at right angles to the I axis of the cap, said cylindrical portion having a cylindrical bore with diametrically arranged openings in its upper and lower walls, a drum-like valve fitting in the bore, with one end of the valve enlarged to form a handle, this enlarged portion having a groove therein, a projection on the cylindrical portion of the cap fitting in said groove,

the other end of the valve being upset to hold the valve in the cylindrical portion of the cap, said valve having a diametrically arranged slot therein for registering with the openings in the upper and lower walls of the cylindrical portion of the cap when the valve is moved to a certain position and said valve having a notch in one wall of the slot for placing the slot in communication with the interior of the cap part when the valve is in closed position.

In testimony whereof I affix my signature.
